At the time we were paying 1k per jam. It wasn't bad, and our roomies also had multiple accounts. The true money maker was ripe fruit sales at another property. Between the two methods we never had an issue keeping up with payouts or being in the top 5 for a few months. This is before the exploit when rampid back in 2005. Payouts ranged from 300-1k depending on the property. On the official launch expect most sims at skill houses.
